Viessmann 7855596 Radial Fan
The Viessmann 7855596 Radial Fan is a precision-engineered OEM replacement part designed for Vitodens 100-W B1HA and B1KA series condensing boilers. As a critical NRG118 combustion blower, this component features a high-durability die-cast aluminum housing and a steel impeller, specifically balanced to maintain the exact air-fuel ratio required for efficient premix combustion. Whether you are servicing a B1HA 26/35 or B1KA 26/35 residential wall-mounted unit, this radial fan assembly provides the static pressure necessary to overcome heat exchanger resistance and ensure reliable flue gas evacuation.
Integrated with sophisticated electronic controls, the ebm-papst NRG118 motor technology delivers consistent modulation for optimized boiler airflow. This 7855596 blower motor is a direct-fit solution that eliminates compatibility issues often found with aftermarket alternatives. Its compact architecture and ball-bearing motor design are optimized for low-noise operation and long-term 120V/60Hz performance in high-efficiency heating systems.
Key Benefits for Technicians:- Genuine Viessmann OEM Quality: Ensures seamless communication with the boiler’s control board for precise RPM modulation and safety monitoring.
- Optimized Combustion Efficiency: Maintains the required primary air-gas mix to prevent resonance or flame lift-off in Vitodens 100-W burners.
- Professional Construction: Utilizes a rugged die-cast aluminum casing that resists corrosion and thermal stress during peak operation.
- Direct Troubleshooting Solution: Resolves common boiler fault codes related to fan speed errors or combustion failure.
Is the 7855596 fan compatible with older WB1B Vitodens models?
No, this specific NRG118 fan assembly is engineered for the B1HA and B1KA 26/35 series. For older WB1B or WB1A models, verification of the specific part number is required as the motor mounting and electrical connectors may differ.
What are the signs that my Viessmann radial fan needs replacement?
Common indicators include high-pitched bearing noise, intermittent F4 or F6 fault codes (ignition or burner errors), or a complete failure to initiate the pre-purge cycle during startup.
Does this assembly include the necessary burner gaskets?
While this part is the primary radial fan assembly, it is a professional best practice to inspect and/or replace the burner tube gaskets and O-?? during installation to ensure a gas-tight seal.
